Letters Patent No. 96,149, dated October 26, 1869; antedatcd October llo, 1869.

MPROVED SHUTTER-W'ORKER.

The Schedule referred to in these Letters Patent and making part of the name.

all persons to whom these presents may come Be it known that I, EnAsTUs W. Scorer, of Wauregan, in the county of \Vindh`am, and State of Connecticut, have invented a new and useful Mechanism for Operating a \Virldo\v-Blind; and d0 hereby de*-` clare ,the same tobe fully described in the following specification, and represented in the accompanying drawings, of whichl Figure l is a front elevation of a window-frame and a blind provided with my invention.

Figure 2 is a vertical and transverse section, taken through the operative spindle.

Figure 3 is a horizontal section, taken through the lower part of the blind.

The mechanism is to effect the opening and closing of the blind, as well as the opening and closing of its series of slats.

Inthe drawings- A denotes the window-frame, and B the blind,- the latter being hinged to the former, as shown at a.. a,

The lower hinge of the blind is provided with a bracket or arm, b, which projects fromthe windowf'rame, and directly over and on the upper end of the v hinge, 'in order to keep the blind from rising while being put in motion.

There extends transversely through the window ame a spindle, C, which is encompassed by' a tube or sleeve, D, having a knob, E, fixed to its inner end.

The sleeve slides freely on the spindle, and is kept in connection therewith hy a stud, c, which projects from the-spindle into a slot, d, formed lengthwise on the sleeve.

At its outer end the slot is turned at a right angle, orV has a notch, e, leading from it, in manner as shown in Figure 4, which is a top view of the sleeve D and the spindle C.

By turning the sleeve so as to bring the stud into the notch, and by forcing endwise on the tube or sleeve, or by pulling it back, an end-wise motion may be imparted to the spindle.

The spindle may also be revolved by revolving thc tube.

The tube or sleeve, so combined with the knob and the spindle, is to enable the knob to be moved forward underneath the window-seat f, so as to be out of the way when not in use.

' The spindle, at its outer end, has an arm, g,pro jecting from it at a right angle to it. i

v The said arm extends through a slot, h, made in a metallic plate, i, fastened to the blind, and arranged therewith in manner as represented.

The arm goes between two arms h l, one of which extends from a latch, F, and the other from the impelling-pawl .G of a ratchet, H.

The latch F is to operate with. two catches I K,

goes through an arm, n., extended ing at one end against the projectionn, and at the.y other against an arm, p, which extends up from the,

latch in manner as represented serves to advance the latch,and to retract the pawi, as occasion may re` quire.

Another spring, q, attached at its lower end to the pawl, and at its upper end to theupper part of 'theA arm p, is to draw the pawl upto the periphery of the ratchet.

Furthermore, the latch, near its front end, foes through a guide, r, extended from theblind.

'lhe ratchet H, placed against the middle of the lower bar of the blind-fran1e, is held thereto by a screw, S, such ratchet being free to revolve thereon. Y

The ratchet is connected with' theoperative bar t of the series of slats u lu u, &'c., of the blind, by means of a connection-rod, r, which. is pivoted to the said bar at its lower end, and to a crank-pin, w, extended from the ratchet. Figure 5 represents a transverse section of the blind, showing the bar t, and its connections with the slats, each of suoli connections consisting of two staples,- x y, one of which is hooked into the other. One` of them is driven into the bar, and the other into the slat.

If, now, we suppose the blind open, and wc desire to close it, we first lay hold ofthe knob, and draw it vand the sleeve back on the spindle. Next we turn the knob, so as to canse the. arm of the spindle to retract the latch, in a manner to unlatch the blind with the back catch. Next we press the spindle forward, so as to move the blind rat-her more than ninety degrees on its hinges, after which the spindle is to be drawn backwarthso as to cause the blind to close and the latch to engage with the inner catch.

Te caneiect the disengagement of the latch from the inner catch, and the subsequent opening movements ot the blind, in a similar way by the knob and spindle.

By means ofthe said knob and spindle, we can also so move the pawl as to turn the ratchet more or less, in order to eii'ect the closing or the opening of the blind-slats.

From the above, it will be seen that we not only I have a means of operating the blind from within the building or apartment thereof containing the window, but also have a means by which a person, while in such apartment, can also, by his hand applied to the knob, effect the opening or closing of the slats of the blind.

I claim the combination and-armngement of the I sleeve D, slotted and recessed, as described, with the knob E, the spindle C, the stud c, the arm g, the slotted plate i, and the spring-latch F, to operate with catches I K, applied to 'the Window-frame A and the building, as explained.

I also claim the arrangement of the latch F, the
